This question wasn't easy to answer because there wasn't a clear definition of the two concepts of " Naruto's number one beauty " and " One Piece's number one beauty." If she was referring to the number one beauty in Naruto or One Piece, then there might not be a clear answer. However, if we view this question as a contest of looks, then I can provide some information. In literary works, the image and appearance of the characters were usually secondary. What was important was the character, behavior, and role setting. Therefore, whether it was Naruto or the beauty in One Piece, their appearance evaluation might not be the most important. In Naruto, Okami, who was known as the " First Beauty of Naruto ", was a very charming and powerful female character. However, her appearance was not as outstanding as her intelligence and strength. Amongst One Piece, the empress, who was known as the " One Piece's number one beauty," was an extremely charismatic and powerful female character. Her appearance was not outstanding, but she had a unique charm and temperament that could attract the attention and love of many men. Therefore, whether it was Naruto or the beauty in One Piece, their appearance evaluation might not be the most important. What was important was their character, behavior, and character setting, as well as the charm and strength they showed in the story.
